る。[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a submersible culture device for fish, shellfish, and seaweed on the sea surface. The present invention relates to an aquaculture device that enables aquaculture at a water depth appropriate for the growth of aquaculture organisms, evacuation of aquaculture organisms to a depth of water that is not affected by red tide, etc.
浮沈式養殖装置としては、特開昭５２−１４１９７号公
報、特開昭５７−１７４９１号公報等に記載されている
ものが知られている。As float-and-sink aquaculture devices, those described in Japanese Patent Application Laid-open Nos. 52-14197 and 1987-17491 are known.

によって、浮沈体の浮上、沈下させること、バランサー
の海底への着底で沈降が停止することを特徴としている
。Accordingly, in the device described in JP-A-52-14197, a fish net is suspended in the internal space of a frame-shaped floating body having a buoyancy adjustment chamber, and the amount of seawater in the buoyancy adjustment chamber is adjusted. It is characterized by the fact that floating objects float and sink, and the sinking stops when the balancer reaches the bottom of the seabed.
一方、特開昭５７−１７４９１号公報に記載のものは、
いけす本体に気体の充填制御が可能な浮力制御部を設け
、水中浮力体といけす本体及び係留索の水中重量をバラ
ンスさせて、いけす本体の沈下速度。On the other hand, the one described in JP-A-57-17491 is
The main body of the fish tank is equipped with a buoyancy control unit that can control the filling of gas, and the underwater weight of the buoyant body, the main body of the fish tank, and the mooring cables are balanced to control the sinking speed of the main body of the fish tank.
沈下深度を制御するようにしたことを特徴としている。The feature is that the sinking depth is controlled.
一般に、いけすは水面に浮いている時は浮力により安定
しているが、水中に没すると安定性を失い、姿勢が不安
定となる。In general, when a fish tank is floating on the water surface, it is stable due to buoyancy, but when it is submerged in water, it loses its stability and becomes unstable.
従って、いけすの姿勢を常に安定に保つためには、いけ
す枠が適当な剛性を有し、垂直方向（深さ方向）及び水
平方向に所定位置を保ち、然も、いけす枠が傾かないよ
う、何らかの拘束がなされる必要がある。Therefore, in order to keep the cage stable at all times, the cage frame must have appropriate rigidity, maintain a predetermined position vertically (depthwise) and horizontally, and prevent the cage frame from tilting. Some kind of restraint needs to be put in place.
然し乍ら、前述の従来公知の装置は、浮力調整機能をい
けす本体に持たせるようになっており。However, in the conventionally known device described above, the buoyancy adjustment function is provided in the main body of the fish tank.
いけすが角型である場合、通常いけすの４隅にそれぞれ
浮力調整機能を持たせなければならないため、連通管を

傾くのを防止するようにしているが、複数個の浮力調整
機能を持つが故に、１個所でも浮力調整機能が破れると
、いけすはその安定性を失なうという共通の問題点があ
る。If the fish tank is rectangular, it is usually necessary to have a buoyancy adjustment function at each of the four corners of the fish tank, so connecting pipes are used to equalize the buoyancy of the four corners to prevent the fish frame from tipping. However, because they have multiple buoyancy adjustment functions, there is a common problem that if the buoyancy adjustment function is broken at even one point, the fish tank will lose its stability.

故につながるという問題点がある。Also, what is described in Japanese Patent Application Laid-Open No. 52-14197 is
Compared to conventional cage frames, it is inappropriate because it requires a large-scale dedicated cage frame, water pollution is expected as the balancer lands on the seabed, and no measures have been taken to prevent the mooring rope from loosening when it sinks. There are problems such as the lack of lateral restraint, and on the other hand,
The cage described in No. 91 has appropriate restraints to maintain the posture of the cage underwater, but it is difficult to adjust the buoyancy by delicately controlling air pressure, and it requires multiple buoyancy bodies and multiple buoyancy adjustment parts. There is a problem that damage to any of them can lead to an accident.
